Yes I am probably reading too much into this, but just for fun here goes...

A natural nuclear fission reactor is a uranium deposit where self-sustaining nuclear chain reactions have occurred. This can be examined by analysis of isotope ratios. The existence of this phenomenon was discovered in 1972 at Oklo in Gabon, Africa, by French physicist Francis Perrin. The conditions under which a natural nuclear reactor could exist had been predicted in 1956 by Paul Kazuo Kuroda. The conditions found were very similar to what was predicted. - source (https://en.wikipedia.org/wiki/Natural_nuclear_fission_reactor)

There is strong geochemical evidence that the Oklo uranium deposit behaved as a natural nuclear fission reactor in Precambrian times: some of the mined uranium was found to have a lower concentration of uranium-235 than expected, as if it had already been in a reactor. Geologists found that it had been in a reactor before — two billion years ago. - source (https://en.wikipedia.org/wiki/Oklo)

The Iboga tree is the central pillar of the Bwiti spiritual practice in West-Central Africa, mainly Gabon, Cameroon and the Republic of the Congo, which uses the alkaloid-containing roots of the plant in a number of ceremonies. - source (https://en.wikipedia.org/wiki/Tabernanthe_iboga)

From my Iboga Report (http://forum.alchemyforums.com/showthread.php?3386-Iboga-Report)(my most important vision):

It is hard to say in what order things came, but very early on I saw an ancient landscape... flat, barren... it was an African savannah at least 10 000 years ago [this number is not fixed, it could be millions as well]. Mountains covered the horizon. It felt as if there was a wind... sand blowing in the air. An old woman with a shawl wrapped around her head Muslim style (but she was not a Muslim) came walking up to an old crocked tree.

She used a walking staff and at the top of hung a lantern. I understood she was a leader/chief of sorts... a strict and strong woman. She turned her head and looked at me. In her hand she held some sort of metallic orb, inside this a light was shining. She extended her hand towards me, showing me this light but not giving it to me.
